Motor winding failures
Low voltage causes motors to draw excess current, overheating windings and shortening service life.

The problem Gurukrupa solves
Unstable voltage is silently damaging your equipment — and your output.
In most Indian industrial areas, three-phase voltage swings between 340 V and 480 V against equipment rated for 415 V. That gap doesn't just shorten equipment life — it burns motor windings, trips CNC controllers, corrupts production runs, and shows up on your maintenance bill every month.
CNC & controller trips
Voltage spikes and sags cause unexpected shutdowns, lost production time and part rejects.
Premature equipment failure
Anything with a power supply inside is vulnerable. Replacement and repair costs accumulate quietly.
Gurukrupa's servo stabilizers fix this. Continuously. At ±1% accuracy.
Air-Cooled Stabilizers
Indoor sites. Clean rooms.
Up to ~500 kVA.
Air-cooled servo stabilizers run cleaner and are easier to service. No oil containment needed. Class F insulation. The right choice for standard indoor commercial and industrial electrical rooms.
- Easier and lower-cost servicing
- No oil containment or spill risk
- Class F insulation for indoor use
- Suited to indoor electrical rooms up to ~500 kVA
- Fast response — corrects within milliseconds

Oil-Cooled Stabilizers
Heavy duty. High ambient.
500 kVA and beyond.
Oil-cooled units carry heat better at high load and in high ambient temperatures — which is why they cover larger ratings and suit outdoor installation. If your site runs heavy continuous duty or sits in an open yard, this is the right choice.
- Superior heat dissipation at high ratings and high ambient
- Suits outdoor installation without de-rating
- Handles heavy continuous industrial duty
- Class A insulation for transformer winding longevity
- Built for rural feeder and harsh grid conditions

Not just a stabilizer.
A complete power solution.
01
Site-built specification
We measure your actual input voltage range first. Every stabilizer is spec'd to your site — not handed over from a fixed catalogue.
02
Authorized OEM supply
We supply from established Indian manufacturers — Golden Servo and Sentronics — built to IS:9815. Not grey-market or unverified stock.
03
Professional installation
Our own engineers install and commission every unit. No subcontracting, no handover to the customer to figure out.
04
145+ centres, 24/7 support
Gurukrupa's service network covers all major cities and industrial belts. A unit outside a metro is not left waiting a week for an engineer.
Applications
Built for the equipment you can least afford to lose.
A plant engineer watching a moulding line reject parts every afternoon is usually watching a voltage problem, not a machine fault.

"We hereby confirm that Gurukrupa Enterprises has been supplying us BPE make 15kVA UPS and 150 kVA Servo Stabilizer (Air Cooled). We are currently happy with their equipments and their service level provided. The stabilizer provided to us is of very high reliability. We will continue using these UPS and stabilizer supplied by Gurukrupa Enterprises."
Specifications
Built to your site.
Not a catalogue guess.
Give us your voltage window, connected load, phase configuration and ambient conditions. We size the unit precisely — and a free power audit measures your real input range first, because sizing against a guessed swing is either overspent or undersized.
Both show up later — on the bill or on the shop floor.

One honest boundary
A stabilizer is not a UPS.
It corrects voltage but cannot carry your load through a power cut — it draws from the same mains it is regulating. Sites that need both steady voltage and ride-through during outages pair a stabilizer with an online UPS. Gurukrupa specifies and supplies both together where the application calls for it.

Questions about servo stabilizers.
What size servo stabilizer do I need?
Sizing starts with two numbers: your real input-voltage swing (measured, not guessed) and your connected load in kVA. We run a free on-site power audit to capture both, then size the unit precisely — because a stabilizer sized against a guessed swing is either overspent or undersized, and both show up later on the bill or on the shop floor.
What is the difference between air-cooled and oil-cooled servo stabilizers?
Air-cooled units are simpler to service, have no oil-containment requirement, and suit indoor commercial and industrial rooms up to about 500 kVA. Oil-cooled units carry heat better at high load and in high ambient temperatures — they cover 500 kVA to 2000 kVA and suit outdoor or heavy continuous-duty installations. We spec one or the other based on your load and site conditions.
Is a servo stabilizer the same as a UPS?
No. A stabilizer corrects voltage but cannot carry your load through a power cut — it draws from the same mains it is regulating. A UPS carries the load through outages via battery. Sites that need both steady voltage AND ride-through pair a stabilizer with an online UPS. Gurukrupa specifies and supplies both together where the application calls for it.
Do you supply single-phase and three-phase stabilizers?
Yes — both. Single-phase and three-phase units, air- and oil-cooled, from 1 kVA to 2000 kVA. All built to IS:9815. The right configuration is determined during the audit, based on your load type and phase balance.
What output accuracy do the stabilizers hold?
Standard output regulation is ±1% no-load to full-load. For sensitive loads (MRI, CT and other diagnostic imaging equipment), we can spec tighter ±2% or better with dedicated topologies. Fast response — corrections happen within milliseconds, not seconds.
Do you provide installation, service, and AMC?
Yes. Our own engineers install and commission every unit — no subcontracting. Service is backed by 145+ PAN-India service centres with 24/7 support. AMC coverage is available with preventive-visit schedules and response-time SLAs written into the contract, not agreed verbally.
